Question:

The parameters of the circuit shown in Figure 4.32 are $V^{+}=3.3 \mathrm{~V}$, $V^{-}=-3.3 \mathrm{~V}, R_{G}=50 \mathrm{k} \Omega, R_{L}=4 \mathrm{k} \Omega, R_{\mathrm{Si}}=0$, and $I_{Q}=2 \mathrm{~mA}$. The transistor parameters are $V_{T N}=0.6 \mathrm{~V}, K_{n}=4 \mathrm{~mA} / \mathrm{V}^{2}$, and $\lambda=0$.

(a) Find $R_{D}$ such that $V_{D S Q}=3.5 \mathrm{~V}$.

(b) Determine the small-signal parameters $g_{m}$ and $R_{i}$.

(c) Find the small-signal voltage gain $A_{v}$.
